Quanzhou Ausenist Technology Co., Ltd Ausenist YS620 Variable Frequency Drive: Complete Technical Specs & Differentiated Advantages for Global Pump Export Market
Ausenist YS620 series is an intelligent constant pressure water supply VFD specially developed for pump equipment, widely exported to Latin America including Panama, Brazil and other Spanish/Portuguese-speaking regions. Unlike general-purpose industrial inverters, the whole hardware and software algorithm of YS620 are optimized for centrifugal pumps, submersible pumps, booster pumps and fire protection pump groups, forming multiple irreplaceable core strengths for overseas integrators, pump OEM manufacturers and distributors.
1. Multi-Pump Parallel Redundant Control System (Core Selling Point)
The YS620 supports a maximum of 6 units parallel connection. In actual overseas engineering projects, the most common matching schemes are 2 to 4 pumps linked, and there is no completed project adopting full 6-unit parallel so far. It adopts dual main pump backup logic: one primary host plus up to 4 auxiliary pumps. Once the main drive encounters communication failure, sensor damage or hardware breakdown, the standby main unit will automatically take over the entire system to ensure uninterrupted water supply.Other intelligent pump control functions include fault skip and timed alternating pump operation (default 8-hour cycle). The system automatically avoids failed pumps during group operation and evenly distributes running hours for all pumps, effectively reducing wear and extending the overall service life of pump sets.
2. Dual RS485 Communication Exclusive Advantage Over YS820 Series
The biggest technical gap between YS620 and YS820 lies in communication ports at low power segments:
- YS620: Full power range (0.75kW ~7.5kW) equipped with dual RS485 interfaces, supporting multi-machine linkage and remote monitoring simultaneously
- YS820: Single RS485 port on 0.75kW & 2.2kW 220V models; only 380V high-power models carry dual RS485For Latin American large irrigation stations and fire water supply projects requiring centralized PLC monitoring, YS620 dual RS485 design brings stronger expandability and stable signal transmission, which is the preferred model for system integrators.
3. Dual Motor Compatibility: PMSM & Asynchronous Motor All-in-One
YS620 realizes one drive for two motor types, compatible with both ordinary three-phase induction motors and permanent magnet synchronous motors. This dual-purpose design greatly reduces customers’ inventory pressure, as one model can match two mainstream pump motor types without purchasing separate inverters for different equipment.
4. IP54 Backpack Mount & Universal Installation Structure
All YS620 inverters reach IP54 dustproof and waterproof grade, adapting to outdoor farm irrigation, open-air fire pump rooms and humid industrial workshops. The backpack-type structure can be directly installed on the junction box of any brand pump, eliminating the need for large independent control cabinets and saving cabinet space and wiring labor costs for overseas customers. A universal mounting plate is equipped as standard; users only need to select matching mounting screws according to pump terminal box dimensions. Besides pump direct mounting, wall-mounted installation is also supported.
5. Comprehensive Multi-Dimensional Protection Functions
Rich built-in safety protection solves common failure risks of overseas water supply systems:
- Environment protection: Intelligent anti-freezing and anti-rust program to prevent pump jamming under low-temperature idle state
- Pipeline protection: Automatic shutdown upon pipe burst, high/low water pressure alarm
- Power & equipment protection: Water shortage protection, input/output phase loss protection, soft start to eliminate water hammer impact on pipelines
- Energy-saving logic: Advanced PID constant pressure algorithm + automatic sleep function when no water consumption, cutting power consumption significantly for agricultural and municipal water supply.
6. Global Wide Voltage & Custom Voltage Service
Standard factory stock models cover 208–230V and 460V, perfectly matching Panama and North American industrial power grids with 50/60Hz dual frequency support. Special 440V/460V customized voltage versions are available with a minimum order quantity of 10 units; customized drives carry higher unit price and longer production lead time than standard stock products.
7. Standard Sensor Wiring & Matching Five-Way Valve Accessories
Unified pressure sensor wiring standard simplifies overseas on-site commissioning: red wire connects to 24V terminal, black wire connects to common C terminal, avoiding miswiring errors by local maintenance technicians. Matching five-way valve accessories support customized interface sizes according to customer pipeline drawings for irrigation and fire pump set supporting export.
Supporting Multilingual Documents for Latin America
Complete Spanish YS620 operation manual and Spanish quotation PDF templates are provided for Panama, Mexico, Colombia and other Spanish-speaking markets. Brazilian Portuguese version materials are also available for South American clients. All inquiry, quotation and after-sales technical replies can be sent in customers’ native minor languages to eliminate communication barriers.
